I've stayed in downtown San Francisco many times for business, but traveling with my family, and spending several days exploring inside the city, I was keen for something further out to retreat to, and took a chance that this wouldn't be too far out for our trips into the city. It typically took us just 20 minutes to get to the city, and with five people, this was a significant bargain over hotel rooms or rentals in the city.
Being able to park in the garage was a huge advantage, both for security and to stay out of the frequent fog. We enjoyed late-night Olympics watching from the large sectional, and played games at the large dining table. It's a great location for families, and the host was amazingly communicative and flexible.
